What it does

The Holding Cost Calculator totals every expense incurred while owning a property before resale — loan interest, property taxes, insurance, utilities, security, lawn care, property management — to show the true cost of time in property. Model holding periods from 3 months to 2 years to see how timeline affects total cost.

Holding costs punish extended timelines, making speed-to-sale critical for flip profitability. This calculator reveals the cost of construction delays and market timing mistakes so you understand why aggressive project management and realistic timelines are profit imperatives.

Who it's for

  • Fix-and-flip operators optimizing project timelines to minimize holding costs
  • Project managers prioritizing critical path items to accelerate completion
  • Hard money lenders evaluating deal timelines and holding cost impact on profitability
  • Contractors understanding how construction delays directly reduce flip profits

Frequently asked questions

What's the average holding period for a flip?

3–6 months with active work; up to 12+ months if holding for market conditions. Each extra month costs $2K–$5K.

Should I include opportunity cost of capital?

Implicitly yes, through interest expense. Direct it: if you borrowed at 8%, your money cost is 8%. If you used cash, you foregone 8% returns elsewhere.

Does holding cost include the sales commission?

No — that's a closing cost, not a holding cost. But both reduce your net profit.

How do I justify a 12-month hold?

If you're waiting for market appreciation or significant value-add, the compounded holding cost needs to be outweighed by the higher sale price. Run the math.

Is this calculator free to use?

Yes — create a free Investor Starter account to run 1 calculator per day. No credit card required. Upgrade to Core ($49/mo) for unlimited access to all 67 calculators.
